The most popular material or grade for hydraulic cylinder honed tube and pipe.

When we are choosing material, we need to consider their MOQ and their mechanical properties at the same time.

If the sizes of hydraulic cylinder honed tubes are standard, many customer will choose material ST52/E355/Q345B. For this material, the MOQ is only 5 ton for each size , and they have good mechanical properties at the same time.

But when the sizes are not standard and can not be cold drawn , only can be machined to get honed tubing, customer will maybe consider material Ck45 / 45#, when without cold drawn, this material has better mechanical properties than ST52/E355/Q345B.

If customer need higher mechanical properties, we can choose to do quenched and tempered treatment.

For honed pipes manufacturer like us, most of our stock material is 20# / A106B, which is the most material in market. 

We would like to send following tables for customers to make comparison :

Table 1 : Chemical Composition Comparison

Table 2: Mechanical Properties (after cold drawn and + SR or BKS)

Table 3 : Mechanical Properties (not cold drawn pipe, but do machined fabrication directly to get honed tube)

Table 4 : Mechanical Properties (after quenched and tempered)
